Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi

I try to modify the example code let it can connect to the Blood Pressure (loading...
Hi, I have written some code following an example for my nRF51-DK using a sensor and HeartRateService, but I tried to use some apps and the scan doesn't seem to see my phone...
Hi.
I have a custom board based on the nRF51822. Application uses s130, SDK 11.0.0. It's a peripheral. Using gcc.
I'm finding that when field testing my device, it will...
Hello,
I'm trying to measure the time difference between two pulses using GPIOTE, PPI and a Timer.
My platform is:
nRF52832
SoftDevice S132 v2.0
My thinking is to...
without timer it work fine but when i use timer it goes here.
my timer code is this
#define APP_TIMER_PRESCALER 0 /**< Value of the RTC1 PRESCALER register. */
